[Mesa3d-users] OpenVG: Why is this not a star?

[Nicholas L. <Nic...@gm...>]

Can anyone tell me why this doesn't draw a star with 5 equal sides?  I can't
figure out what concept I have wrong.

Here's what I'm doing:

VGubyte close[] = {VG_CLOSE_PATH};
VGubyte cmds[] = {VG_LINE_TO_REL};
VGfloat coords[] = {200.0, 0.0};

VGImage star = vgCreatePath(...);
VGImage line = vgCreatePath(...);

vgAppendPathData(line, 1, cmds, coords);

vgSeti(VG_MATRIX_MODE, VG_MATRIX_PATH_USER_TO_SURFACE);
vgLoadIdentity();

for(i=0; i<4; i++)
{
  vgTransformPath(star, line);
  vgRotate(-144.0);
}

vgAppendPathData(star, 1, close, coords);

...

vgLoadIdentity();
vgTranslate(imgWidth/2, imgHeight/2);
vgDrawPath(star, VG_STROKE_PATH);

and I'm getting the attached image (why are the lengths messed up?):
